Question

the total cost of 3 tables and 2 chairs is rs8745.If a table cost rs40 more than a chair, find the price of each​

Answer 1

Step-by-step explanation:

total cost of 3 tables and 2 chairs = 8745/-

and table cost is 40/- more than a chair

let the cost of chair be ' x '

let the cost of table = x + 40

taking table = T and chair = C

3T + 2C = 8745/-

3 ( x + 40 ) + 2 ( x ) = 8745/-

3x + 120 + 2x = 8745

5x + 120 = 8745

5x = 8745 - 120

5x = 8625

x = 8625/5

x = 1725/-

so the cost of single chair = x = 1725/-

and cost of two chairs = 1725 × 2 = 3450/-

cost of single table = x + 40 = 1725 + 40 = 1765/-

cost of three chairs = 3 ( 1765 ) = 5295/-
